Patterns of Marijuana Use and Physical Health Indicators Among Canadian Youth

The current study adds to our growing understanding of the health of Canadian youth with differing marijuana use trajectories by examining how marijuana use fre- quency is related to physical health indicators in ado- lescence and young adulthood. We extend past research by examining how trajectories of marijuana use are related to multiple physical health indicators; subjective health, health-promoting behaviours, body mass index, serious injuries and sexual risk behaviours.

Adolescent Patterns of Peer Victimization - Concurrent and Longitudinal Health Correlates

We examine how heterogeneity in adolescent experiences of peer victimization impact health in adolescence and young adulthood. We include multiple indicators of mental health - internalizing symptoms (i.e., depressive and anxiety symptoms), externalizing symptoms (i.e., attention deficit hyperactivity disorder (ADHD) symptoms, oppositional defiant disorder (ODD) symptoms, and conduct problems), and substance use (i.e., smoking, heavy drinking, marijuana and illicit drug use). We also use multiple measures of physical health - subjective health (i.e., physical symptoms and physical self-concept), health-promoting behaviors (i.e., physical activity, healthy eating practices, and sleep duration and problems), and cardiometabolic risks (i.e., BMI waist circumference, and hypertension). In examining young adult health, we directly control for earlier (i.e., baseline) symptoms in order account for stability in health over time.

Associations Between Marijuana Use Trajectories and Educational and Occupational Success in Young Adulthood

This study examines the associations between these trajectory groups and multiple indicators of economic well-being in young adulthood (ages 22 to 29) to investigate which specific aspects of economic well-being were more likely to be impacted negatively by marijuana use.

Poly-victimization and Trajectories of Binge Drinking from Adolescence to Young Adulthood among Serious Juvenile Offenders

In the present study, we examine a sample of juvenile justice involved youth from adolescence to young adulthood to determine theeffect of multiple violence exposures on the development of binge drinking.

Effect of Victimization on Impulse Control and Binge Drinking among Serious Juvenile Offenders from Adolescence to Young Adulthood

The current study investigates the associations between victimization, binge drinking, and impulse control from adolescence to young adulthood in a sample of early-onset justice involved youth.

Social Ecological Determinants of Substance Use Treatment Entry Among Serious Juvenile Offenders From Adolescence Through Emering Adulthood

Applying a social–ecological framework, this study aims to fill a gap in the literature by investigating factors in various domains (individual, familial, peer, and neighborhood) separately and simultaneously to determine risk and protective factors for treatment entry among serious juvenile offenders over the course of 7 years.

The Longitudinal Associations Between Substance Use, Crime, and Social Risk Among Emerging Adults - A Longitudinal Within- and Between-Person Latent Variables Analysis

The current study examined the reciprocal relationships between crime, substance use, and social risk among emerging adults (aged 18–25 years) in substance use treatment.
